Yellow! See above. Do you know where your Yellows are? Mine are right on my screen. Not lacking in the least. I don't need no stinkin yellow pixel glowers. I got yellow in my pix popping right out at me and saying hello! -------------------- Mark William Rabiner Photography mark at rabinergroup.com > From: Lawrence Zeitlin <lrzeitlin at gmail.com> > Reply-To: Leica Users Group <lug at leica-users.org> > Date: Fri, 13 Aug 2010 14:52:05 -0400 > To: Leica Users Group <lug at leica-users.org> > Subject: [Leica] Fourth color > > I just saw an advertisement noting that Sharp has added yellow as a fourth > color to its LCD TV screens.
